IOS development based on Baidu map (3) -- address search

Poi search in the previous article can search for poi in a specific range around the specified location. If you want to search for "Beijing" in Shanghai People's Square, poi returns a list of Beijing Roast Duck shops nearby. For this reason, sometimes we need to identify whether the user-entered search content is an address. here we need to use the address search described in this article.

1. Search first

Bmksearch * search = [[bmksearch alloc] init]; // create a search object search. delegate = self; // when the proxy is set to itself, the function [search geocode: "Beijing" withcity: @ ""] in the next step is automatically called back after the search. // search for Beijing // [Search release]; // Note: release is not supported. Otherwise, it cannot be searched. Define search as a member variable.

2. Process search results

- (void)onGetAddrResult:(BMKAddrInfo*)result errorCode:(int)error{    if (error == BMKErrorOk) {        BMKPointAnnotation* item = [[BMKPointAnnotation alloc]init];        item.coordinate = result.strAddr;        item.title = result.geoPt;        [mapView addAnnotation:item];        [item release];    }}

The above callback will automatically display the searched poi on the map through annotation.
